Great! You are aweeeeeeeeeesomee! You are something! You give a crystal clear explanation!

Just what I had determined. Thanks.

This is an excellent video, but sin cos and tan still just appear in a puff of presupposing green smoke. I am after an explanation of *sin* like what does it DO what IS it, where did it come from? How did anyone even think to deduce that there was some mystical function that you multiply an angle by to get the ratio of two perpendicular lines? This video already assumes knowledge and understanding of the trig functions existence. It is like asking how does a car engine work to move it forwards what are the intricacies and workings of its innermost parts to make liquid into motion, and the response is: " well the engine starts and the car moves by turning liquid into movement". I KNOW, but how does the engine itself work, what does it DO to the petrol to make liquid into motion???!!!

I know this comment is 4 years old, but this is the exact same predicament I'm in right now! I think the best way I can think of it myself is almost in a programming/computer science sense. Sin is a name for a function(or method) that, given the parameter of the angle theta, will then return to you the ratio between what it found to be the y component of the point on the circle,(the 'opposite') to the radius(hypotenuse). TLDR: sin is just a shorthand name mathematicians gave to the quotient value of opposite/hypotenuse with theta as referance.

@@ClaireGrob There is no time on the internet! That's a good explanation, but it doesn't tell me WHAT sin does, what it the formula or process sin does on the value to get the result.
